Security vulnerabilities have been identified in the Intel® 2200BG and 2100 PRO/Wireless Network Connection Hardware. Sony is now investigating this issue and expediting the update program verification. Although Sony has not received any report from customers, as it involves a security issue, we would like to take it seriously and provide the up-to-date information and present countermeasures to remedy this issue.

Security vulnerabilities exist in the Intel® 2200BG PRO/Wireless Network Connection Hardware, which could potentially be exploited by attackers within range of the Wi-Fi station to execute arbitrary code on the target system with kernel-level privileges. This symptom is due to a memory corruption while passing certain frames.
